Y., ASSIGNOR TO H. A. WILSON COMPANY,

INDICATOR FOR TEMPERATURE CONTROLS..

Application filed June 6,

To (/ZZ whom it may concern.'

lie it known that I, lViLLAin) I. '.lwonrnnr, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Indicators for Temperature Controls, of which the following is a specification.

My invention relates to an indicator' enibodied in devices for cont-rolling temperatures. More specifically, my invention relates to an indicator adapted for use in connection with a control for governing the tem.- pcrature of ovens for gas stoves. I will describe an indicator embodying my invention and then point out the novel features thereof in claims.

In the accompanying drawing Fig. 1 is a perspective view of an indicator embodying my invention. Fig. 2 is a vertical crosssect-ional View of the indicator shown in Fig. 1. Fig. 3 is a plan view of a cooking chart used in connection with the indicator.

Similar letters of reference designate co1'- rcs'ponding parts in all of the figures.

'lhe regulator may be used in connection with any type of temperature control designed to be set for any temperature and to maintain that temperature. For example it may be used in connection. with the therinostatic control set forth in an'application for Letters Patent, tiled by me May 1, i922, Ser. No. 557,669; or with the control set forth in an application for Letters Patent tiled by nic May 2G, 1922, Ser. No. 563.769.

Referring now to the drawings, the indicator comprises a base A here shown as being cup shaped and having an opening a to receive that part of the control which sets the parts thereof to maintain the temperature for which the control is set. B designates a cooking chart here shown as being in the form of an elongated strip, which 1 is mounted upon the base A and suitable se- 1922. Serial No. 566,425.

cured thereon. C designates a cover for the vend wall of the base and it is secured therestuffs b1, and the periods of time b2, required to cook the food-stuffs. If desired the chart may also contain the figures of the temperature divisions. Instead of using a separate part B maintaining it on the base A, the information for cooking may be applied directly to the base A. It Will be understood that a fixed pointer (not shown) is used in connection with the indicator. By turning the indicator relatively to the pointer, the name of any food-stuit ina be brought under the pointer. lVhen this is done the operator will then know that the control with Which the indicator is associated is then set to maintain the temperature necessary to cook that food-stuff. After that all that is required is to note the length of time required to cook the food-stuff.

lVhat I claim as my inventionis:

1. An indicator for temperature controls for cooking ovens, comprising a part adapted for connection with the setting means of the control, and a cooking chart carried thereby and containing food-stuffs arranged in accordance With the temperatures necessary to cook them.

2. An indicatorv for temperature controls for cooking oven, comprising a part adapted for connection With the setting means of the control, and a cooking chart carried thereby and containing food-stuffs arrai'iged in accordance with the temperatures necessary to cook them, and the length of time for cooking at such temperature.
